Title: Glycoprotein gp105 on bl3 hematopoietic stem cells
Inventor: WONG PETER M C
IPC: C07K14/705
Filed: 1996-06-06
Abstract: An N-glycosylated glycoprotein, having the molecular weight of 105 kDa when glycosylated and 85 kDa when non-glycosylated, is present on the surface of BL3 hematopoietic stem cells, but is absent from the surfaces of other cells including 32D and FDC-P1 myeloid progenitor cells, EL4 T-cells and 3T3 fibroblasts. Antibody which binds the gp105 protein inhibits the proliferation of BL3 cells that occurs in BL3-conditioned medium (BL3CM). It also can inhibit preferentially the formation of fetal liver cell-derived, multilineage colonies in vitro, and the development of bone marrow cell-derived, spleen cells colony-forming unit foci in vivo. Anti-gp105 antibody can be employed in making a preparation that is enriched for hematopoietic stem cells. Substantially purified from other proteins, the gp105 protein itself is a useful reagent for isolating and characterizing the factor(s) responsible for the proliferative effect of BL3CM.

Patent CA-2225421-A1 (CA)
Inventor: GOSSEN RALF
IPC: B65C9/20
Filed: 1996-06-24
Abstract: The invention concerns an adhesive system for sticking all-round labels, said system comprising a priming adhesive which is active whilst the label is applied and a covering adhesive for permanently sticking the label overlap. At its application temperature, the priming adhesive has significantly higher adhesiveness, measured as tensile strength, than at its conventional storage temperature. In addition, this adhesive has greater affinity to the label than to the hollow body bearing this label. Consequently, the label can easily be removed from the hollow body without leaving residues of adhesive. If, nevertheless, a residue of adhesive should remain on the hollow body, it can advantageously be dissolved by an alkaline solution.

Title: Vacuum assisted web drive for corrugator double backer
Inventor: TOURDOT MATTHEW A
IPC: B65G21/20
Filed: 1997-06-25
Abstract: A double backer (10) for curing the web bonding adhesive and drying the corrugated paperboard web (11) utilizes a web holddown apparatus for maintaining the web in intimate drying contact with the lower heating units which does not require the use of a driven holddown belt. The web is pulled through the double backer (10) by a downstream vacuum conveyor section (23) comprising a single full width belt (92) to the upper surfaces of which a vacuum is applied. The vacuum drive belt (92) has low friction strips (2, 7) on the underside by which the belt is supported on vacuum plenum support surfaces (97) and a unique pattern of vacuum distribution channels (105) on the other side of the belt which together reduce friction and drive power requirements.

Title: Heater system for a flat panel such as a liquid crystal display
Inventor: PILKINGTON GORDON T
IPC: G02F1/136
Filed: 1995-07-31
Abstract: A flat panel such as a liquid crystal display (20) includes an array of pixels (24) arranged in rows and columns. A gate line (26) interconnects each row of the array while a source line (28) interconnects each column of the array.  Redundant gate drives (30) are connected to opposed ends of the gate lines and are controlled to select the pixels in one of the rows by driving the gate line of that selected row to a logic high condition. Data can be written to one or more pixels in the selected row by supplying data to the source lines connected to those pixels. In order to heat the LCD panel or maintain its temperature during operation, the gate drives can also be controlled to create a potential voltage difference across some or all of the gate lines. When the potential voltage difference exists, current flows in the gate lines.  Electrical resistive losses result in the dissipation of heat within the liquid crystal display.

Title: Disk type inverter-stacker with improved sheet handling slots for different paper weights
Inventor: KEYES THOMAS C
IPC: B65H29/06
Filed: 1998-02-06
Abstract: In a disk type sheet inverting and stacking system with rotatable disk units with sheet transporting slots, in which printed sheets outputted by a reproduction system are sequentially fed into those slots to be inverted by rotation of the disk units and then released from the slots at a stacking position, the sheet transporting slots of said disk units are provided with a convolute sheet path formed by plural internal sheet corrugating protuberances extending transversely across the slot from opposite sides of the slot, spaced along the slot, to form a convolute sheet corrugating sheet path within the slot to automatically increase the retention force of the sheet within the slot in proportion to an increase in the thickness or stiffness of the sheet, without substantially increasing the resistance to lateral movement of the sheet within the slot. These protuberances have smoothly arcuate large diameter surfaces, with small surface angles in the direction of sheet insertion, to provide relatively low resistance to the insertion of a sheet into the slots.

Patent CA-2232243-A1 (CA)
Inventor: NELSON CHRISTINE D
IPC: G01J3/28
Filed: 1998-03-16
Abstract: A system for normalizing measurement obtained from spectrometers to correct for measurement biases in individual spectrometers. The normalization system is adapted for use in spectrometers having an optical assembly for obtaining characteristic data from a test sample. A normalization factor is obtained in each spectrometer by placing a holographic dispersion filter between the light source and detector in the position normally occupied by the test sample, the filter having been encoded with a symbol representing a nominal value of light expected to pass through the filter. The spectrometer a determines the value of light passing through the filter and calculates a normalization factor based on the ratio between the nominal value of the filter and the actual value obtained by the spectrometer. The normalization factor is stored in system memory and the filter removed so that the spectrometer may thereafter be used toevaluate a plurality of test samples. The measured results obtained from the test samples are normalized by multiplying them by the stored normalization factor. Where measurements are obtained from a plurality of spectrometers, the normalized results vary less than about 10% from instrument to instrument for a variety of types ofcharacteristic data, including turbidimetric microalbumin assays.

Title: A floor structure of a vehicle
Inventor: TAKAHASHI TOSHIKI
IPC: B62D25/20
Filed: 1998-03-16
Abstract: In a floor structure of a vehicle comprising: left and right side sills; a substantially flat floor panel extending between the left and right side sills; and a cross member for connecting the left and right side sills, the cross member comprises: left and right upper members which extend inwardly from the left and right side sills, respectively, and attached to a top surface of the floor panel with their opposing inward ends spaced from each other; and a lower member extending laterally across a part of a lateral length of the vehicle and attached to an under surface of the floor panel. In the above floor structure, an open space formed beside the lower member can accommodate external piping under the floor panel, and the floor surface can be substantially flat by placing front seats over the upper members. Thus, a floor structure is achieved in which the floor surface is substantially flat and the floor is placed at a lower position.      The upper and lower members connected via the floor panel can ensure sufficient rigidity of the floor structure.

Abstract: Méthode permettant de déterminer les variations de couleurs d'une zone dans un espace d'affichage en définissant, notamment, une surface paramétrique bicubique autour de la zone. Cette surface comprend : quatre coins, chacun des coins étant associé à une couleur; et quatre courbes reliant des paires de coins formant une boucle fermée. Les quatre courbes définissent les variations de couleurs de la surface paramétrique bicubique en fonction des quatre couleurs attribuées aux quatre coins de la surface paramétrique bicubique. La méthode consiste à définir une maille dans un espace de paramètre, y compris une fonction de mappage de la maille jusqu'à la surface paramétrique bicubique, de sorte que les coins de la surface paramétrique bicubique soient en correspondance jusqu'aux coins de la maille. La couleur de chaque point de la maille est une interpolation bicubique des quatre couleurs associées aux quatre coins de la surface paramétrique bicubique. La méthode consiste en outre à détourer la surface paramétrique bicubique pour afficher la zone. Dans une autre version, on fait état d'une méthode permettant de rendre avec précision les variations de couleurs d'une surface paramétrique bicubique. Cette méthode consiste : à subdiviser la surface paramétrique bicubique en sous-surfaces jusqu'à ce que chaque côté d'une surface paramétrique bicubique donnée produise une bonne approximation d'une ligne; et à procéder à une vérification afin de déterminer si, pour chaque point à l'intérieur d'une sous-surface donnée, la couleur associée à chaque point est suffisamment juste. Si ce n'est pas le cas, la sous-surface est subdivisée davantage jusqu'à ce que la couleur associée à chaque point à l'intérieur d'une sous-section donnée soit suffisamment juste. Il s'agit de diviser les sous-surfaces en polygones et de reproduire les polygones.
